Vortex rings propagating through a rotating fluid, along the axis of rotation, are studied experimentally. The length, x(d), traveled by the rings until they have completely decayed is measured. In agreement with theoretical arguments based on the Taylor-Proudman theorem it is observed that the value of x(d) decreases with decreasing Rossby number, Ro. For the parameter range investigated here we determine an overall, global trend for the scaling of the mean decay length that can be roughly summarized by the expression (x(d)/D)=4.77 Ro(1.06), where D is the diameter of the generator nozzle used to produce the vortex rings.
